If the helium is "contaminated" with a >small amount of hydrogen (0.04 %) this time is divided by about 10. Having a limited education in cryogenics is hampering my understanding of this phenomenon. I understood that helium cannot exist in liquid state at 6 Atm. I can't see how one may "contaminate" it, either. Would someone kindly enlighten me?
